Electric tools is a frequently used tool in labor, the electric shock accident rate is very high. So we should be how to prevent electric tool to get an electric shock? Below small make up to introduce some related measures. , building construction site in general should choose class II hand-held power tools, and should configure rated leakage current action is not more than mA, rated leakage action time is less than. S of the leakage protector, if the use of type I tools, in addition to the above measures, the tools themselves must also be protected by zero. , according to the degree of danger into workplace choice sheep corresponding category of hand-held power tools, and, according to the requirements of specification strictly adopt measures to prevent electric shock. And in highly dangerous places with a class III hand electric tools, by the low voltage isolation transformer. If you choose class II tools, you must according to the demand of the leakage protector. Transformer and leakage protector in the workplace, someone care while working. , wet places in the open, or metal frame, must choose class II hand-held power tools, configuration and preventing leakage protector; Like the previous rated leakage current action and time requirements. I kind of electric tools is strictly prohibited in such places. , tools used in the power plug socket must be intact, and internal wiring can't loose, it is forbidden to use plug connected to the power supply, prevent the zero line break. , hand-held electric tools, before use to check the power cord switch shell, can not have damaged insulation cracking phenomenon, joint wants firm, switch to be flexible. After electrify to do light check, functioning rear can formal operation. , hand-held power tools of the power cord must meet the national standard requirements, shall not be any extension or replace, the green/yellow double-color wire under any circumstances can only be zero line protection. , plug socket must match, to ensure that the moderately elastic, when the plug and socket contact closely, are not allowed to insert the plug of the poles 3 pole plug from the socket. , tool distribution must use just one brake a leakage, banned one brake is multi-purpose. Blade leakage protector should be located in a door with a cover of electric in the box. , tool power socket installation wants firm, so that the work to take unplug when not is driven. In order not to let loose connection plug damage, don't pull when unplug the power cord. Transfer the workplace, the power cord should be collected, can't drag on the ground. Keepers, tools, deposited in the warehouse, the routine inspection, full-time staff conduct regular check, check items and contents according to the provisions of national standard. And maintenance when conducted by professionals. During maintenance, should first take out the power plug and power on again after work. End of the maintenance, the original insulation parts shall not be dismantling and packing.
